Definitions

  • a liquid crystal composition further comprising a third component consisting of at least one compound selected from the group consisting of compounds expressed by formula (V) or (VI): R 4 ⁇ A ⁇ Z 3 ⁇ B ⁇ R 5 wherein, in formula (V) R 4 and R 5 each represent independently an alkyl group of 1 to 10 carbon atoms in which one or two non-adjacent methylene group(s) may be substituted by an oxygen atom; A and B each represent independently trans-1,4-cyclohexylene or 1,4-phenylene; and Z 3 represents -CH 2 CH 2 - or a single bond, and in formula (VI) R 6 represents an alkyl group of 1 to 10 carbon atoms; R 7 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms; C and D each represent independently trans-1,4-cyclohexylene or 1,4-phenylene.
  • composition is expressed in per cent by weight and a voltage holding ratio is determined by area ratio method wherein integrated voltage per cycle time is expressed by the area.
